A new 2023 translation directly from the original manuscripts into English of Descartes' famous work "The World, or the Treatise of the light". This edition contains a new introduction and afterword from the translator, as well as a timeline of Descartes' life and summaries of each of his works. Here, he explores the nature of light and its interaction with matter. It is significant because it helped to establish the idea of light as a wave and had a significant impact on the development of modern physics.

This volume preserves the format in which Discourse on Method was originally published: as a preface to Descartes's writings on optics, geometry, and meteorology. In his introduction, Olscamp discusses the value of reading the Discourse alongside these three works, which sheds new light on Descartes's method. Includes an updated bibliography.

The long chains of simple and easy reasonings by means of which geometers are accustomed to reach the conclusions of their most difficult demonstrations, had led me to imagine that all things, the knowledge of which is competent to man, are mutually connected in the same way, and that there is nothing so far removed from us as to be beyond our reach, or so hidden that we cannot discover it, provided only we abstain from accepting the false for the true, and always preserve in our thoughts the order necessary for the deduction of one truth from another. from Part II Sometimes called the father of modern philosophy, French mathematician, scientist, and writer RENE DESCARTES (15961650) continues to have a deeply profound impact on our modern world. His thinking on how the mind works and what is it capable of has profoundly impacted our understanding of ourselveshe summed up his philosophy with the phrase I think, therefore I am, which still thrills usand his influence extends to our own experiments with modern computing and artificial intelligence. This treatise on the value of doubt and skepticism when studying the natural world laid the foundation for the modern scientific method as we still employ it today, as well as the basis for modern philosophy. It is impossible to overstate how vital this work is to the entirety of human culture as it stands in the 21st century. Written in French and first published in 1637 under the full title Discourse on the Method of Rightly Conducting the Reason, and Seeking Truth in the Sciences, it is here presented in the 1901 edition of the 1850 English translation by Scottish poet, philosopher, and historian JOHN VEITCH (18291894).

René Descartes, (born March 31, 1596, La Haye, Touraine, France-died February 11, 1650, Stockholm, Sweden), French mathematician, scientist, and philosopher. Because he was one of the first to abandon Scholastic Aristotelianism, because he formulated the first modern version of mind-body dualism, from which stems the mind-body problem, and because he promoted the development of a new science grounded in observation and experiment, he has been called the father of modern philosophy. Applying an original system of methodical doubt, he dismissed apparent knowledge derived from authority, the senses, and reason and erected new epistemic foundations on the basis of the intuition that, when he is thinking, he exists; this he expressed in the dictum "I think, therefore I am" (best known in its Latin formulation, "Cogito, ergo sum," though originally written in French, "Je pense, donc je suis"). He developed a metaphysical dualism that distinguishes radically between mind, the essence of which is thinking, and matter, the essence of which is extension in three dimensions. Descartes's metaphysics is rationalist, based on the postulation of innate ideas of mind, matter, and God, but his physics and physiology, based on sensory experience, are mechanistic and empiricist. Descartes's Discourse on Method (1637) is one of the first important modern philosophical works not written in Latin. Descartes said that he wrote in French so that all who had good sense, including women, could read his work and learn to think for themselves. He believed that everyone could tell true from false by the natural light of reason. In three essays accompanying the Discourse, he illustrated his method for utilizing reason in the search for truth in the sciences: in Dioptrics he derived the law of refraction, in Meteorology he explained the rainbow, and in Geometry he gave an exposition of his analytic geometry. He also perfected the system invented by François Viète for representing known numerical quantities with a, b, c, ..., unknowns with x, y, z, ..., and squares, cubes, and other powers with numerical superscripts, as in x2, x3, ..., which made algebraic calculations much easier than they had been before. In the Discourse he also provided a provisional moral code (later presented as final) for use while seeking truth: (1) obey local customs and laws, (2) make decisions on the best evidence and then stick to them firmly as though they were certain, (3) change desires rather than the world, and (4) always seek truth. This code exhibits Descartes's prudential conservatism, decisiveness, stoicism, and dedication. The Discourse and other works illustrate Descartes's conception of knowledge as being like a tree in its interconnectedness and in the grounding provided to higher forms of knowledge by lower or more fundamental ones. Thus, for Descartes, metaphysics corresponds to the roots of the tree, physics to the trunk, and medicine, mechanics, and morals to the branches.

Presents the philosopher's most important work, one that proves the existence of the self and God, and explains the physical world.

"The effect of this man on his age and the new age cannot be imagined broadly enough... René Descartes is indeed the true beginner of modern philosophy, insofar as it makes thinking the principle. "- Hegel "Descartes was the first to bring to light the idea of a transcendental science, which is to contain a system of knowledge of the conditions of possibility of all knowledge." - Kant "Descartes is rightly considered the father of modern philosophy" - Schopenhauer A new 2023 translation directly from the original manuscripts into English of Descartes' famous work "The World, or the Treatise of the light".
